This isn't necessarily an indication of boredom. Feather-plucking is an activity they will do if bored. Parrots eat their flooring just because, by nature, they like to shred things.
They will pick at their feathers, eat, rip up flooring in their cage (if you have any for them to rip that is.) If their wings are not clipped they may fly.

If your parakeet hates you, it is instinctively reacting to you, since you are tremendously larger than it, as a possible predator who might eat it.
This is a simple answer. They are vegetarian. they eat nothing but seeds and nuts YOUR WELCOME.
Can they eat strawberries? Yes, I feed them to my parakeet all the time.
Probably leting you know he want out. Or he just likes the sound of it or is bored. Does your bird have plenty of toys to play with.
